DRV8353RS-EVM: writing register permanently

Part Number: DRV8353RS-EVM


When I write to the gate driver register using SPI from another MCU, the gate driver register is successfully written. But when I exit the debugging mode of the firmware or power the board off, then restart and read the same register, the register contains its default value. Is the register memory permanent? Or do I have to write the register to change the settings of the gate driver every time on startup?
